Applications installed through Nix (and home-manager) are not showing up

[sylvesterroos]

When I install an application through Nix (or it's companion home-manager) it doesn't show up in Junction. A quick look through Junction's settings in Flatseal make it obvious that it doesn't have permission for those directories. I tried giving Junction permission to these directories, but it's not working. Am I doing something wrong, or lies this problem in Junction's behavior?

As you can see, both files contain the HTTPS mimetype:

cat .nix-profile/share/applications/org.gnome.Epiphany.desktop

[perkons]

I have the same problem. Only in my case it does only show one app - Brave browser. Brave is installed via Home-Manager, so are other Browsers. Not sure why it is like that. This issue should probably be opened under nixpkgs issues.
Here is a workaround:

{ pkgs, ... }:
let
  junction-desktop-item = pkgs.makeDesktopItem {
    name = "Junction";
    desktopName = "Junction";
    genericName = "Junction";
    exec = "re.sonny.Junction %U";
    terminal = false;
    categories = [ "Settings" "System" "Utility" "GNOME" "GTK" ];
    mimeTypes = [ "x-scheme-handler/x-junction" ];
    startupWMClass = "Junction";
  };
in
{

  home.packages = with pkgs; [
    junction
    junction-desktop-item
  ];

}

I don't use Nix so someone will have to figure it out.

Junction has "--filesystem=host:ro", so I don't think the new permissions are needed.

Most likely you need to update https://github.com/sonnyp/Junction/blob/main/src/bin.js#L1
